This is to support a strawberry plant through growth. put each half around the core plant and as the strawberries start to grow they will rest on the support instead of the ground. Keeps a lot of ground-dwelling bugs off of the fruit as well.
The model is cut right down the middle, with three supports for each half. This allows you to change the size of the internal hole as the strawberry plant grows. Ensure each half is far enough away from the other during the print that they don't fuse.
Recommend printing in PETG to ensure the Sun and UV don't ruin it outside over time. These should last several seasons.
